Tunisia (Arabic: تونس Tūnis, officially the Tunisian Republic (الجمهورية التونسية‎), is a country situated on the Mediterranean coast of North Africa. It is the northernmost African country and the smallest of the nations situated along the Atlas mountain range. Around forty percent of the country is composed of the Sahara desert, with much of the remainder consisting of particularly fertile soil, and a 1300-km coastline. Both played a prominent role in ancient times, first with the famous Phoenician city of Carthage, and later, as the Africa Province, which became known as the bread basket of the Roman Empire.
